I've brought an 4GB SD card and I'm dedicating it for use by ReadyBoost (on Windows7)

Im looking to get the most profit on performance, so i've formatted it with exFAT (as recommended by Microsoft) but I have some doubts to define what best .Allocation Unit Size* I should choose.

Since I can't get how ReadyBoost/SD card exactly read/seek the data, can someone tell what make choosing an Allocation Unit Size in favor of another for this scheme ?

Apparently, ReadyBoost is allocating all the free space in SD card as one huge file, so a big Allocation Unit Size is advised for fastest reading time. I'm not confusing with ordinary HDD's ?
